   4         * call.c (null_ptr_cst_p): Strip location wrappers when
   5         converting from '0' to a pointer type in C++11 onwards.
   6         (conversion_null_warnings): Replace comparison with null_node with
   7         call to null_node_p.

  46         (selftest::cp_tree_c_tests): New function.
  47         * typeck.c (string_conv_p): Strip any location wrapper from "exp".
  48         (cp_build_binary_op): Replace comparison with null_node with call
